As kmemleak-test.c is moved to samples dir, it is not compiled if just setting CONFIG_DEBUG_KMEMLEAK_TEST as module and enabling CONFIG_DEBUG_KMEMLEAK. So move the DEBUG_KMEMLEAK_TEST option to samples dir as well and rename it to SAMPLE_KMEMLEAK_TEST. And also replace DEBUG_KMEMLEAK_TEST with SAMPLE_KMEMLEAK_TEST in some other places.

To check if you have all set up to use kmemleak, you can use the kmemleak-test -module, a module that deliberately leaks memory. Set CONFIG_DEBUG_KMEMLEAK_TEST +module, a module that deliberately leaks memory. Set CONFIG_SAMPLE_KMEMLEAK_TEST as module (it can't be used as built-in) and boot the kernel with kmemleak enabled. Load the module and perform a scan with::
